THE IMPACT OF PREOPERATIVE ESOPHAGEAL MANOMETRIC STUDY ON ANTI-REFLUX SURGICAL DECISION: A RETROSPECTIVE STUDY FROM JORDAN

Introduction: Esophageal manometry is an endoscopic study of the esophagus motility and can diagnose dysmotility disorders and the tone of the gastro-esophageal sphincter. The main aim of the study is to identify the role of esophageal manometry in surgery decision-making and to determine which type of fundoplication is required for gastric reflux disease. Methodology: it’s a retrospective of 210 patients with gastroesophageal reflux disease, who underwent endoscopic esophageal manometry in order to undergo anti-reflux surgery. The study was conducted at King Hussein Medical Hospital. We collected data retrospectively from the electronic medical recording system regarding all patients who performed the test from August 2022 to July 2025. All patients who were planned to undergo antireflux surgery and underwent esophageal manometry as a preoperative preparation were included in this study, whereas the patients who underwent the test because of dysphagia or esophageal dysmotility were excluded from the study. Then, we followed the surgical decision of antireflux surgery to do Nissen or partial Fundoplication accordingly. Medical biostatistical tests and software like SPSS are used to collect data and to measure the results. Results: A total of 210 cases, that underwent preoperative preparations and planned for anti-reflux surgery. The mean age was 49+-0.3 years. A 46 % (n=99) where female patients with slightly higher percentage in male patient (54%, n=111). Manometric study performed for all patient (100%), abnormal study observed in 15 patients (7.2%) that showed significant difference and P-value was than 0.03, most of these dysmotility were a chalasia 10 patients, while the other 5 patients suffered from non-specific abnormal esophageal contractility. Conclusions: esophageal manometry is pivotal preparation test must be performed to delineate the esophageal motility before undergoing anti-reflux procedure, it may change the type of surgical procedure and the degree of fundoplication
